Answer:
You can also use standard deviation to compare two sets of data. For example, a weather reporter is analyzing the high temperature forecasted for two different cities. A low standard deviation would show a reliable weather forecast.

Answer:
The correct answer is option A. Base = 11 cm and height = 13 cm
Step-by-step explanation:
It is given that, height of a triangle is 2 cm more than its base.Then height is increased by 2 cm.Then the area of triangle becomes 82.5 cm²
<u>To find the base an d height of original triangle</u>
Let x be the original base 'b' then the height h = x + 2
New height h = x + 2 + 2 = x + 4
Area = bh/2
82.5= (x(x + 4)/2
165 = x² + 4x
x + 4x - 165 = 0
Solving we get x = 11 and x = -15
Take positive value x = 11
Therefore base = 11 and height = x + 2 = 13 cm
The correct answer is option A. Base = 11 cm and height = 13 cm
Answer:
960
Step-by-step explanation:
x = 0.6x + 384
Subtract 0.6x from both sides.
0.4x = 384
Divide both sides by 0.4
x = 960
<span>If she puts the same amount of confetti in each 5 bags - means that she divides all amount into 5 bags.
So,
4.75 : 5 = 0.95
Answer: each bag should weigh 0.95 pounds.</span>
Answer:
1 / 10 (1 : 10) (10%) - your teacher has probably given you some idea as to the formatting of how you should write probability [so 3 different ways are written here], but I suspect they expect you to write it as 1 / 10
Step-by-step explanation:
only 1 out of all of these 10 trials is a "success" (aka what we are looking for)
we know that 7 matches the criteria of all years seeing a groundhog, and that all other options (1 , 2 , 3 , 4 , 5 , 6 , 8 , 9 , 10) do not meet this criteria.
so, the experimental probability** is 1 / 10 (or 1 : 10) (1 / 10 = 10%)
**: experimental probability is about how many times something happens in the experiment--not theoretically. it means that if his life was destined to be 1 of the 10, the probability of his experience matching the criteria is 1 / 10
experimental probability can be thought of as
successes / possible outcomes
